Open in App
Solution

1st part

We have,

Worker W1=5

Weed a field in days=D1=12days

If,

Take worker W2=6

Then, Days D2=?


Then, we know that,

W1D1=W2D2

5×12=6×D2

D2=5×126

D2=10days

2nd Part,

If workerW3=15

Then,

Days D2=?


Then, we know that,

W1D1=W3D3

5×12=15×D3

D3=5×1215

D3=4days


Hence, this is the answer.
